I am trying to use Gumbo's python wrapper to parse HTML.
My operating system is Ubuntu 14.04.3 LTS. I am using Python2.7
I have cloned the latest version of Gumbo from github.
I followed the installation steps provided on Github.
The installation of the libraries, both the C library and the python wrapper, appeared to be successful ( No error message, both printed successful messages at the end )
C library final message:
Libraries have been installed in: /usr/local/lib
Python wrapper message:
Installed
/usr/local/lib/python2.7/dist-packages/gumbo-0.10.1-py2.7.egg
Processing dependencies for gumbo==0.10.1 Finished processing
dependencies for gumbo==0.10.1
The first problem I encountered was when I tried to open pydoc for gumbo, to better understand the library.
pydoc gumbo produced the following error:
problem in gumbo - <type 'exceptions.OSError'>: /usr/local/lib/python2.7/dist-packages/gumbo-0.10.1-py2.7.egg/gumbo/libgumbo.so: cannot open shared object file: No such file or directory
Searching for the message yielded a single result.
It was not of much use to me.
Looking at the dist-packages directory, I noticed that libgumbo.so was not in /usr/local/lib/python2.7/dist-packages/gumbo-0.10.1-py2.7.egg/gumbo/ . All other files ( soup-adapter.py, gumboc.py, etc ) where there however.
The installation of the C library placed libgumbo.so ( and some other libraries, like libgumbo.a libgumbo.la, etc ) in /usr/local/lib. So, as a work around, I created a simlink from .../dist-packages/gumbo-0.10.1-py2.7.egg/gumbo/ to /usr/local/lib.
This got pydoc gumbo to work.
I tried to import gumbo and soup-adapter in the interpreter after. I received the following error:
import soup_adapter
Traceback (most recent call last):

self._handle = _dlopen(self._name, mode)
OSError: libgumbo.so: cannot open shared object file: No such file or directory
I am not sure how to proceed or how exactly to get gumbo to work.

my issue is that i've been trying to make an exe file with a .py that I created, but it doesn't work. I executed the converted .exe file from the console to see the log and I got this:
Traceback (most recent call last):
File "professors.py", line 10, in <module>
File "PyInstaller\loader\pyimod03_importers.py", line 531, in exec_module

File "importlib\metadata.py", line 187, in from_name
importlib.metadata.PackageNotFoundError: docx2pdf
[6940] Failed to execute script professors
I've been reading about the issue and it seems that pyinstaller doesn't recognize the docx2pdf import. I read in a website that I have to add it in a folder called site-packages, but it is supposed to have another folder inside called pyInstaller, which is not there. I also tried adding the folder manually but it still didn't work. I also tried with the --hidden-imports method but im not sure how to exactly use it.
I will have to apply this to other imports that I have also.
Any ideas? Thanks in advance!
I had a identical issue. I removed lines 7-13 from the docx2pdf module:
try:
# 3.8+
from importlib.metadata import version
except ImportError:
from importlib_metadata import version
__version__ = version(__package__)
and line 119...
print(__version__)
After that, it worked. Modifying the module probably isn't the best solution, and of course I'd recommend backing up the module before modifying it, but I hope it works for you too.
I am using s3cmd to upload files.
and it always upload .png file as "image/x-png" for MIME type.
So I decide to install "python-magic"
What I did here:
Installed Python 2.7 x86 on Windows 7 64bit, (since the manual of "python-magic" said only x86 will work) download from http://www.python.org/download/releases/2.7/
Installed Python Extention Setuptools http://www.lfd.uci.edu/~gohlke/pythonlibs/#setuptools
Download & Installed https://github.com/ahupp/python-magic , use 'C:\Python27\python setup.py install'
Found the 3 files ( magic1.dll, zlib1.dll, regex2.dll, as required by python-magic ) and copied to Windows/System32
ok, at last s3cmd is using python-magic for MIME, BUT errors:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
An unexpected error has occurred.
Please report the following lines to:
s3tools-bugs#lists.sourceforge.net
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Problem: MagicException: could not find any magic files!

Please advice how or where can I get some magic files.
I've never used py2exe before. I installed the package, created a setup.py, ran it and it seemed to work without any obvious errors. I went into the dist folder it created and tried to run the exe but I'm getting this error:
Traceback (most recent call last):
File "rl2.py", line 3, in <module>
File "libtcodpy.pyc", line 41, in <module>

File "ctypes\__init__.pyc", line 353, in __init__
WindowsError: [Error 126] The specified module could not be found
How can I solve this?
What exact commands did you use to get this output?
I recommend using PyInstaller.
You can build an EXE with PyInstaller using this command:
"python pyinstaller.py -y -w -F [PATH\TO\SCRIPT.py] -n [PROJECT_NAME]"
-y: answer yes to every question
-w: windowed (does not show commandline when running)
-F: Compile into one EXE instead of a directory with .dll files
-n: assign project name
Hope I helped
You probably need to manually specify ctypes in the packages section of your setup.py.
See here
I had same issue today. HEre is the solution will work 100%
The meaning of error is the imported dll file in your code is misssng in created dist folder. so you have to copy and paste dll file in dist folder, and it will work.
I used logimove.dll file and same issue. so i put logimove.dll file in dist file and it works. :)
I have created a simple program which uses pywin32. I want to deploy it as an executable, so I py2exe'd it. I also didn't want a huge amount of files, so I set bundle_files to 1 (meaning bundle everything together). However, when I attempt running it, I get:
Traceback (most recent call last):
File "pshelper.py", line 4, in <module>
File "zipextimporter.pyc", line 82, in load_module
File "win32.pyc", line 8, in <module>
File "zipextimporter.pyc", line 98, in load_module
ImportError: MemoryLoadLibrary failed loading win32ui.pyd
In my setup script, I tried doing packages=["win32ui"] and includes=["win32ui"] as options, but that didn't help. How can I get py2exe to include win32ui.pyd?
I don't have this problem if I don't ask it to bundle the files, so I can do that, for now, but I'd like to know how to get it to work properly.
Are you sure that the problem is that win32ui.pyd is not included? The stack trace isn't exactly the same as noted in the wiki, but check this out: http://www.py2exe.org/index.cgi/Py2exeAndWin32ui.
The work-around that has worked best so far is to simply re-implement the pywin32 functions using ctypes. That doesn't require another .pyd or .dll file so the issue is obviated.
Do care to try out PyInstaller? I've used it both on Windows 7 and Ubuntu 10.04 and it worked like magic, even when I compiled to .pyd on Windows.
I've been able to bundle all sorts of applications that I've developed with it.
I have the same problem trying to bundle psutil with py2exe. Here is what I found so far.
Traceback (most recent call last):
File "wx_gui.py", line 43, in <module>
File "zipextimporter.pyc", line 82, in load_module

File "psutil\_psmswindows.pyc", line 15, in <module>
File "zipextimporter.pyc", line 98, in load_module
ImportError: MemoryLoadLibrary failed loading _psutil_mswindows.pyd
I get this traceback when bundle_files = 3. zipfile may be specified or may be None, I still get the problem.
First, I thought this was a missing dll because of this page:
http://www.py2exe.org/index.cgi/ProblemsToBeFixed
I've copied all the dlls I found in Python27 into the same directory as the executable and added that directory path to os.environ['path']. That didn't worked.
Then I tried to import my package directly from site-packages.
I've replaced the whole sys.path of my compiled executable with my normal sys.path
sys.path = [r'C:\Python27\Lib\idlelib', ...]
I think the .pyd module got imported but Visual c++ threw me this really ugly error message:
Runtime Error!
Program: {path}.exe
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
I suggest you try to replace the whole sys.path to see if it is working. If it is, you could always make your single executable write the necessary module into a temp directory and add it to your path. If not, I feel like this problem is going to be hard to solve.
I use one c++ dll in my python code.
When I run my python app on my computer, it works fine but when I copy all to another computer this happen:
Traceback (most recent call last):

WindowsError: [Error 14001] The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail
How can I fix this problem so that my python app work in every computer?
Note:
I only need them to work on windows 7 like mine. And I tested on another win7 computer (both 32bits).
You're using a DLL which depends on a Microsoft Visual C++ runtime which isn't installed on the target computer. You have a few options:
Install or copy the Visual C++ runtime libraries to the target computer. Installation is done by adding merge modules to your installer (if you have one) or by running the redistributable installer (vcredist.exe). The various methods are documented here for VS2005 (other versions will be similar).
If you built the DLL, you can change the project settings to statically link the runtime libraries. See this answer to see how this is done.
